STM32F411 Breakout Board – 100 MHz Cortex-M4F Development Module

Description

Meet the STM32 Breakout — a tiny yet mighty module designed around the STM32F411CEU6 (Cortex-M4F) running at 100 MHz. It features a USB-C connector for power and programming, dual rows of castellated and through-holes for flexible integration, onboard Reset and Boot buttons, an RGB LED, and full compatibility with Arduino, MicroPython, CircuitPython, PlatformIO and STM32Cube-IDE.

Despite its compact size (~28 × 21mm), the STM32 Breakout delivers 512 KB of flash and 128 KB of SRAM, making it ideal for embedded projects, high-performance sensors, robotics, IoT and wearable applications.
